SLIDING-DOOR LOCK.

Application filed November 17, 1913.

To all whom it may concern Be it known that I, FRANCIS CONNAGHAN, acitizen of the United States, residing at Paola, in the county of Miami and State of Kansas, have invented new and useful lmprovements in Sliding-Door Locks, of which the following is a specification.

The present invention relates to sliding door looks, and the primary object is to provide a simple, practicable and novel structure for securing relatively sliding members against separation.

The preferred embodiment of the invention is illustrated in the accompanying drawings, wherein Figure 1 is a side elevation ot1 the lock, with one of the casing walls removed. Fig. 2 is a vertical sectional view therethrough. Fig. 3 is a sectional view on the line 3 3 of Fig. 1. Figs. 4 and 5 are cross sectional views, respectively, on the lines 4-4 and 5 5 of Fig. 1. Fig. 6 is a detail perspective view showing the key-controlling tumbler and the key.

Similar reference numerals designate corresponding parts in all the figures of the drawings.

Tn the embodiment illustrated, the lock member comprises a casing having opposite side walls 6 and 7 with edge walls 8 located between the same, the side walls being tied together by bolts 9, or other suitable fasteners. One of the edge walls 8 is provided with an opening 10 that receives a hasp 11. It will be understood that the lock casing is secured to or in one of a air of relatively sliding members, designated respectively, 12 and 13, and that the hasp is carried by the other member. This hasp has a beveled free end 14 and a socket 15.

Located in the easing, are keepers 16, 17 and 18, which as shown particularly in Figs. 3 and 5, have alined guide eyes 19. The keepers 17 and 18 are disposed close together and on opposite sides of the path of movement of the hasp 11, so that said hasp will pass between said keepers. A bolt 20 has its shank portion slidably mounted in the said keepers transversely of the path of movement of the hasp 11, and is provided with a beveled end 21 that operates across the space between the keepers 17 and 18, the said beveled end 21 cooperating with the beveled end 14 of the hasp 11 so that when said hasp enters the casing, the bolt will be raised until its end alines with the opening or the Speccation of Letters Patent.

socket 15 into which it will drop, thus holding said hasp in locked position, as will be evident. The bolt 20 is provided with an enlarged head 22 providing shoulders 23 that abut against the keeper 16 so as to limit the downward movement of said bolt, and this head furthermore has a key-receiving socket or recess 24 formed in one side of the same, so as to receive the bit 25 of a key 26 entered through a suitable key-hole and journaling on a stud 27 fixed in the case. A leafspring 28, secured at one end between posts 29, and having a bearing against another post 30, bears against the rear end of the head 22 to urge the bolt 20 to locking position.

In order to insure the use of the proper key Jfor actuating the bolt 2O a tumbler 31 is employed that is pivoted in the casing, as shown at 32, and has a free swinging movement between the head 22 and the side wall 6 of the casing. The swinging movement of this tumbler is limited by posts 30 and 33. lt will be observed that the tumbler extends across the key-receiving recess 24 of the head 22, and as shown in Fig. 6 can be cut away more or less so as to permit the pivotal movement of the key bit 25. The opposite wall 7 of the casing carries a Xed key-controlling abutment 34 shown particularly in Figs. 3 and 4, and this abutment can be formed in diiierent shapes so as to require differently shaped keys for operating the lock.

The operation of the structure, it is believed, will be clear, particularly by reference to Fig. 1. then the two members to be locked together are brought sufciently close together, the hasp 11 will enter the casing 6, and be caught by the bolt 20. To unlock the said members, it is necessary therefore to insert the proper key into the casing, so that said key can turn past the tumbler 31 and the abutment 34 and at the same time engage the head 22 and thus withdraw the bolt 20 from the hasp.

From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size, shape, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus fully described my invention,

what I claim as new and desire to secure by Letters Patent7 is In a sliding,` door lock, the combination with a casing, of a hasp that enters the cas- I 5 ing, keepers in the casing` having alined eyes, a reoiprocatory bolt slidable in the eyes transversely of the hasp and spaced by the keepers from both the opposite side walls of the casing, said bolt interlockingat one end with the hasp, the other end of the bolt having an enlarged head forming a shoulder that abats against the adjacent keeper to limit the movement of the bolt, and said head having a key-receiving recess in one l5 side, a key-controllingtumbler pivoted to one side wall and located between said side wall and one side of the bolt head, said tumbler extending across the key-receiving recess, and a key-controlling abutment located on the opposite side wall of the casing be` tween the same and the head and extending across the opposite side of the key-receiving recess.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
